Answer:

6. x = 28 degrees

7.  z = 1.6 cm

Step-by-step explanation:

6.  

Notice that you can use the property that tells us that the addition of all internal angles of a triangle must give 180 degrees, then you write the following equation:

50 + 69 + (2 x +5) = 180

combine like terms:

119 + 2 x + 5 = 180

124 + 2 x = 180

subtract 124 from both sides:

2 x = 56

divide by 2 both sides:

x = 56 / 2

x = 28 degrees

Problem 7.

If the two triangles are congruent, then the side MN must equal side RS.

Since MN  measure 1,8 cm, then RS must also measure 1.8 cm

and we can write the equation:

1.8 = 3 z - 3

adding 3 to both sides:

1.8 + 3 = 3 z

4.8 = 3 z

dividing both sides by 3:

z = 4.8 / 3

z = 1.6 cm

What is the slope in slope-intercept form for these graphs?
Irina-Kira [14]

Answer:

Step-by-step explanation:

for this graph  find rise over run ,  and where the line crosses they y axis.. sooo ..

it crosses at -2 and  the slope is rise over run  or y/x and I can see by the graph that the line goes up 1 when it goes over 1... so the slope is +1

sooo...

use the slope intercept form   y = mx + b

y = 1x + (-2)

y = x - 2   :)

The sum of two numbers is 46. The larger number is two less than three times the smaller number. Find the numbers.‍♀️
Alex787 [66]

Answer:

Smaller number: 12

Larger number: 34

Step-by-step explanation:

Let x represent the smaller number.

Let 3x - 2 represent the larger number (The larger number is two less than three times the smaller number, or x)

x + 3x -2 = 46

   Add 3x + x:

4x - 2 = 46

   Add 2 to both sides:

4x = 46 + 2

   Add 46 + 2:

4x = 48

    Divide both sides by 4:

4x/4 = 48/4

x = 12 is the smaller number

Since 12 is the smaller number, and the sum of the two numbers is 46, than the larger number must be 34.

I hope this helped you. If it did, please consider, rating, pressing thanks and/or giving my answer 'Brainliest.' Have a great day! :)

HELP PLEASE WILL MARK THE BRAINLIEST. Needs to be handed in tomorrow.
Sunny_sXe [5.5K]

Given : ABCF is a Rectangle

⇒ AB = CF

Given : AB = 6 cm

⇒ CF = 6 cm

Perimeter of a Rectangle is given by : 2(Length + Width)

Given : Perimeter of the Rectangle = 20 cm

⇒ 2(6 + BC) = 20

⇒ 6 + BC = 10

⇒ BC = 4

Given : BD = 9

But, We can See that : BD = BC + CD

⇒ CD + 4 = 9

⇒ CD = 5

We know that :

✿  \mathsf{Area\;of\;Trapezium\;is\;given\;by : (\frac{a + b}{2}) \times Height}

Where : a and b are Lengths of Parallel Sides and Height is Length between those Parallel Sides

In the Given Trapezium :

The Parallel Sides are CD and EF and Height is CF

Given : EF = 3 cm

\mathsf{\implies Area\;of\;the\;Given\;Trapezium = (\frac{5 + 3}{2}) \times 6}

\mathsf{\implies Area\;of\;the\;Given\;Trapezium = 24\;cm^2}
